Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The linearized Vlasov and Vlasov-Fokker-Planck equations in a uniform magnetic field
均匀磁场 线性化 Vlasov Vlasov-Foker-Planck方程
2023/5/17
We study the linearized Vlasov equations and the linearized Vlasov-Fokker-Planck equations in the weakly collisional limit in a uniform magnetic field. In both cases, we consider periodic confinement ...
Earth's last magnetic field reversal took far longer than once thought（图）
Earth magnetic field reversal took longer once thought
2019/10/21
Earth's magnetic field seems steady and true -- reliable enough to navigate by. Yet, largely hidden from daily life, the field drifts, waxes and wanes.The magnetic North Pole is currently shifting tow...
Ultracold atoms point toward an intriguing magnetic behavior（图）
Ultracold atoms point toward magnetic behavior
2017/10/25
The researchers found that applying a strong magnetic field to these ultracold atoms caused them to line up in an alternating pattern and lean away from each other. The behavior, which researchers cal...
Nuclear Science and Engineering Associate Professor Nuno Loureiro has spent his first year and a half at MIT’s Plasma Science and Fusion Center (PSFC) exploring the magnetic processes crucial to under...
Aggregation of superparamagnetic colloids in magnetic fields: the quest for the equilibrium state
Aggregation of superparamagnetic magnetic
2010/11/25
Experimental and simulation studies of superparamagnetic colloids in strong external fields have systematically shown an irreversible aggregation process in which chains of particles steadily grow and...

2010/11/19
Effect of Co, Ru and Cu substitution at B and B’ sites on the magnetic and transport properties of LaSrCoRuO6 have been investigated. All the doped compositions crystallize in the monoclinic structure...
Electron transport and anisotropy of the upper critical magnetic field in a Ba0.68K0.32Fe2As2 single crystals
Electron transport anisotropy of the upper critical magnetic field
2010/11/17
Early work on the iron-arsenide compounds supported the view, that a reduced dimensionality might be a necessary prerequisite for high–Tc superconductivity. Later, however, it was found that the zero-...
Magnetization and Magnetoresistance of CeRu2Al10 under High Magnetic Fields along c-Axis
CeRu2Al10 Kondo semiconductor pulsed high magnetic field
2010/11/24
We have studied the magnetization and magnetoresistance of CeRu2Al10 in the applied magnetic field H along the c-axis up to ∼ 55 T. The magnetization M at low temperatures shows an H-linear incr...

2011/1/7
Measurement of the tensor electric and magnetic polarizabilities of the deuteron is of great
interest, especially in connection with the possibilities of COSY and GSI. These polarizabilities can be m...

Possible splitting of deconfinement chiral transitions strong magnetic fields
2011/1/14
We show that finite-temperature deconfinement and chiral transitions can split in a strong enough magnetic field. The splitting in critical temperatures of these transitions in a constant magnetic fie...
